Covering more than half the size of China, the Amazon rainforest,     1     name is got from the Amazon River, plays a significant role in     2     (maintain) the balance of the Earth’s ecosystem.     3     the richest biodiversity on the Earth, the Amazon rainforest’s different levels are home to various living things,     4    (provide) food and shelter for an unbelievable variety of wildlife. Among all the creatures     5     (hide) in the rainforest, the jaguar,     6     is close to extinction, still lives on. As one element of the food chain, jaguars feed on 87 species and in turn will     7     (break) down after death, thus providing nutrition for the Earth. Though     8     (know) as the “lungs of the planet”，much of the Amazon rainforest     9     (disappear) and more species are in danger of extinction. We cannot afford     10     (damage) the “lungs of the planet”．

Xiechi Lake, also known as Yuncheng Salt Lake in China’s Shanxi Province,     1     (become) popular on social media websites in the past few years.

Now, China wants to transform that online     2     (popular) into real-life tourism. “As the Chinese ‘Dead Sea’, floating here is     3     unforgettable experience, and one you can’t find anywhere else,” reads a tourism advertisement     4     (sponsor) by the Yuncheng Salt Lake Tourism Development Company. Yuncheng Salt Lake is a sulfate (硫酸盐) lake. “If the sulfate in your water is greater than the calcium (钙), all the calcium is used up,     5     leaves you with large amounts of sulfate and you have a sulfate lake,” explains geography professor Bernie Owen. Xiechi is also a “closed basin” lake,     6     (mean) it doesn’t flow out to a river or ocean, which explains how its salt content stays so high. It is possible for salt lakes to freeze over, although not as     7     (quick) as other lakes — after all, think about what happens when we spread salt over icy roads. Saltwater freezes at     8    (low) temperatures than fresh water.

In an effort     9     (boost) Xiechi Lake’s international profile, China is reportedly taking steps to get it recognized     10     a UNESCO World Heritage site.

Beijing is a city that straddles(跨越)the divide between the ancient and the modern. It is home     1     more than 3,000 years of fascinating history, and a place     2     fully embraces the fast-paced development of modern life, with high-rise 21st-century architectural wonders standing side by side with cultural relics of the past.

This integration of styles     3     (be) strikingly typical at Zhihua Temple, built in 1444 during the rule of emperor Zhengtong. Though much smaller now than at its peak of 20,000 square meters, the temple is a somewhat     4     (hide) treasure.

    5     (remarkable), the temple museum offers a collection of remains and statues. You might even forget you’re in the 2lst century, if not for the smooth curve of the modern Galaxy Soho building looming over the mythical beasts(神兽)seated on the ridges(屋脊)of the temple roofs.

Yet     6     they belong to completely different     7     (era),   appearances and purposes, they are both equally representative of this city. Seeing the two together is a perfect example of the idea of how respecting our history, while still     8     (look)to the future, can create a truly unique cityscape.

The development of this city, which is carefully designed     9     (protect)the past while embracing the modern world,    10     (mean)there is always something new to discover here, and I could be photographing Beijing for the next 50 years and still not have scratched the surface, which is part of its beauty.

The Lion Rock mountain stands not only as one of the most famous scenic spots in Hong Kong,     1     has become a spiritual symbol representing the persistent efforts of ordinary Hong Kong people     2     (live) a better life.

The Lion Rock spirit has also     3     (deep) touched those outside Hong Kong, such as Cui Xiaodong,     4     ink artist and director of the Yan Huang Art Museum in Bejing. “The mountain stands like a giant, symbolizing the industrious and persistent spirit which, over the past decades,     5     (pull) people in Hong Kong together through hard times. It is a recollection of the youth and vigor (活力) of a generation of people in Hong Kong     6     struggled to make the city what it is today.” he says.

Cui created Lion Rock in Hong Kong, a colored ink painting. In his painting, Cui depicts (描绘) the cliffs of the Lion Rock, surrounded by blooming trees and     7     (overlook) the city’s skyscrapers. Made earlier this year, the painting is now     8     show at Greater Bay Area in the Eyes of Artists, a display marking the 25th anniversary of the Hong Kong Special Administrative Region. The     9     (exhibit) displayed there hail (向……致敬) the ecological diversity of the area and also presents to the audience     10     (success) reformative accomplishments since 1997.

9 . The country’s first national park, Yellowstone, is renaming one of its largest mountains to honor indigenous people after research revealed the man it had been named after helped lead a massacre (屠杀) against local tribes. As part of the park’s 150th anniversary, officials announced the 10,551-foot high peak formerly called Mount Doane is now First Peoples Mountain.

“It is a victory, yes. Is history being rewritten and retold truthfully? I hope so,” William Snell, executive director of the Rocky Mountain Tribal Leaders Council, told NPR. His group helped advise federal officials on the name change. In an email, Snell said the change to First Peoples Mountain couldn't have come at a better time as Yellowstone officials prepare for the park’s anniversary in August.

The peak—along a range on the eastern side of Yellowstone Lake—had been named after Gustavus Doane, who helped lead the Washburn-Langford-Doane exploration in 1870 that eventually led to the park getting federal protection.

But recently, historians uncovered Doane’s role in an attack that left at least 173 Native Americans dead. Known as the Marias Massacre, Doane carried out the attack over the killing of a white fur trader. In writings, Doane cast a favorable light on the attack and even showed off about it for the rest of his life, the National Park Service said last week.

The renaming to First Peoples Mountain is part of a trend to better recognize the roles and contributions of Native Americans. It has also become a priority of the nation’s first indigenous cabinet secretary—the Interior Department’s Deb Haaland, who oversees the National Park Service—and Charles SamsⅢ, the first Native American to serve as that agency’s director.

Across the American West, many iconic representative mountains and other environmental places were named after early white settlers, mostly men and some with terrible pasts.

In Yellowstone, park officials say they may consider further changes to derogatory (贬损的) or inappropriate geographical names in the months ahead.
